Reflection symmetry, reflectional symmetry, line symmetry, mirror symmetry, mirror-image symmetry, or bilateral symmetry is symmetry with respect to reflection
None - it has rotational symmetry - not reflection symmetry.

reflection
Nope - it has rotational symmetry.
It depends on which type of cuboid we are talking about. If it is a CUBE (a special type of cuboid), then it has nine planes of symmetry. If it is a cuboid with length, width and height all different, then it has three planes of symmetry. If it is a cuboid with two equal measurements (say width and length), then it has five planes of symmetry.
A cuboid has three orthogonal two-fold axes of symmetry through its centre. It also has three planes of mirror symmetry.
